CP200 Series Secondary Seat™ Protection does not provide additional overpressure protection in the event the secondary seat or disk is damaged by debris or contamination in the pipeline, or from conditions that would cause the regulator to go wide-open.

CP200 Series • Install the regulator with the vent pointed vertically down, see Figure 4. If the vent cannot be installed in a vertically down position, the regulator must be installed under a separate protective cover. Installing the regulator with the vent down allows condensation to drain, minimizes the entry of water or other debris from entering the vent, and minimizes vent blockage from freezing precipitation.

CP200 Series Maintenance ! Warning To avoid personal injury or equipment damage, do not attempt any maintenance or disassembly without first isolating the regulator from system pressure and relieving all internal pressure as described in “Shutdown”. Regulators that have been disassembled for repair must be tested for proper operation before being returned to service. Only parts manufactured by Regulator Technologies should be used for repairing Fisher® regulators.

CP200 Series 2. Inspect the removed parts for damage and debris. Replace any damaged parts. 3. To remove the valve cartridge assembly, grasp the end of the cartridge (key 10) and pull it straight out of the body (key 1). Replace with new cartridge assembly. The cartridge assembly may be disassembled and parts may be cleaned or replaced. If the soft seat (key 15) was removed, make sure it is properly snapped into place before installing the valve cartridge assembly. 4.
